With conventional drainage, the pipe needs to be installed with enough grade that the water flowing through the pipe will have enough velocity that contaminants won’t clog the system over time, thus the term “self cleaning velocity.” Self Cleaning Velocity in drainage manuals is stated as a minimum flow of 3 feet per second. At this flow rate, a pipe will be flushed of contaminants and remain open.
The slope needed for a pipe to maintain this velocity is based on the Manning number of the pipe. This number calculates the friction as the result of wall construction and diameter. It is generally accepted that smoothwall 4″ pipe placed at a 1% slope will provide adequate velocity in a system …
Drainage Siphons can be indispensable on difficult properties. Park Meadows C.C. in Park City, UT hired TDA to design a drainage system to help them handle the spring snow melt that plagued their golf course. The Turf Drain Siphon System that was installed throughout the golf course was ideal for the flat property. John Haynes, CGCS, superintendent at Park Meadows, says, “The system really was amazing. The amount of water we removed was much greater and faster than I had expected.”
The Turf Drain Siphon System is typically used in flat coastal properties, like Seminole Golf Club, where the elevation across the property is minimal, but it can also be used in mountain properties where rocky soils present difficulties grading …
There are a couple of projects currently being installed by contractors. Call us at 800-999-2794 if you would have an interest in visiting a job site.
Highlands C.C. is a historic course that was the summer home of Bobby Jones. Siphon Systems, Inc. is working with Brian to install a drainage plan done by TDA that includes work on 4 holes. The work includes removal and replacement of metal culvert, installation of basins, and extensive seepage drainage, as well as the installation of two pumps on low lying holes. You can also see one of the sod harvesters in operation here. These sod harvesters can …
